Hi,
made a small PCB for 're-purposing' displays with a quite unusual resolution.

The display is a Sharp LQ060B3DW02 5.98in display in a quite unusual aspect ratio: 768x128pixels.

Sharp LQ060B3DW02 connected to Raspberry Pi Zero

The module has a 18-bit (color) RGB interface which allows to use it on the DPI interface of the Raspberry. Since the Raspberry can not support this resolution a custom hdmi timing is needed (refer to viewtopic.php?f=29&t=24679&p=1010860#p1010860).

As you can see '-win' command does the 'magic' of positioning the video tiles, while 'screen' starts four different consoles. Note that I've included '-b' (black background) option in each console. This will prevent one sees the desktop when a 'video tile' is finished (far left movie (Big Buck Bunny trailer) i.e.).

It's a neat little PCB, and there's nothing esoteric going on there (microcontrollers, FPGA, other "LCD driving" hardware, etc). Those displays are really interesting; their form factor is so unlike what you'd normally encounter. I have a couple of projects I want to get off the ground, and some of them involve custom carrier PCBs and driving LCDs directly from the Pi (using SPI). I can already see how I'd put one of these LCDs to use!

I had a go at soldering a 50-pin FFC connector for use on a breakout board, and more recently on a 10-pin FFC breakout I designed myself. I think it's fair to say that my soldering skills are not yet up to the task of 0.5mm pin pitch SMD work! FFC connectors are probably not the best introduction to SMD soldering.... Ah well, I guess it means that I'll be building my reflow oven sooner than I'd planned!

Subscribed to this thread love weird things like this , here's a idea you know them marquees on the top of arcade machines , if you scaled a cab to the screen you have. It would be awesome mini video version of this http://youtu.be/DTg7XHteBTE

We're could I find one of them screens is it a salvaged part ? Are you planning on selling your dev boards or is it a personal play around project?

Keep up the good work

Thanks!

Wow, that's pretty cool. The guy in the video is using an image file on the small screen; as you can see from the video you can even let OMXplayer play one (or more) video files from a Pi Zero.

I had the idea of trying to get these screens working with the Pi when I found NOS (new old stock) displays here: http://www.pollin.de/shop/dt/MTQxOTc4OT ... 5DW01.html
EUR3.95 is incredibly cheap for a TFT so not a big risk for spending some money by clicking the order button ....

Got the larger one working but had some noise in the picture. That's why I decided to develop an adapter PCB, pretty much at the same time when I got hands on the Zero V1.3. The rest is now history

I have some PCBs left which I will sell at cost. Will PM you with some details.

O.K. .. then let me make your mouth watery now:

active screen size comparison to 7in WVGA display - neat fit

But to be honest: I think this video got me now! You know, there's an 'how to build your own arcade machine' in the last/current revision of MagPi; will have to download the plans, buy some wood and get them milled.... shouldn't the to hard to change the design files to make them accept a Marquee top (as an add-on i.e. since it will be fully self contained) ...

Would like to use them for the "TFT-LCD-Modul SHARP LQ092B5DW01" and some RPI Zero, just need them to run some animations that react on some rfid, so is the board using all the gpio? Or will it be possible to connect an RFID-rc522 at the same time? So would like the optimal board for this screen...

Don't know your RFID module/chip requirements. The display can best be used with mode5 or mode6 from the table below. See if one of them will leave the GPIO for your RFID available (I'm using mode5 here)

Just thought that you already have made a board for the LQ092B5DW01 because I saw that you have postet a picture of the screen, and a link on where you buy them. I'm a really NooB so don't know how to make the board, I can solder yes but have no clue on how to make the PCB. The RFID use the SPI, so think it can share that part. The color scheme you have shown here with the different GPIO connections, what does the different colors mean?

Hi,
yes, I have made a PCB for the LQ092B5DW01 but since I still need to find the right settings for this screen I will not make it available. Once it's running I will open a new tread on the LQ092B5DW01.

Well, might sound simple, but it isn't! You're asking about the meaning of the different colors in the GPIO diagram ... so maybe this is not the right project for you to start with!
The displays - both LQ060B3DW02 and LQ092B5DW01- are 18-bit RGB displays. That translates to 666 = 6 bit for each color. That's what you see in the GPIO diagram. It shows the different color assignments for the supported operating modes.
I'm using the LQ060B3DW02 in mode 5 --> GPIO 4 to 21 were used for the color data. GPIO 0 to 3 were required in addition (refer to https://www.raspberrypi.org/documentati ... /README.md for details on the DPI interface). This let's you use GPIO 22 to 27 for other things.
